I have a 2000 la sabre limited, 170,000 miles. Great running car. With the rear windows, you can hear the motors run but nothing happens with the windows. Is this the regulator, cable, or what? Also, how difficult to fix? Additionally, my steering wheel lights do not work. I can get the switches out of the steering wheel but the lights look like little blue LED lights that are soldered to a little circut board.

Lately when I start the car I have been getting a CHECK ENGINE light that stays on. I then shut it off and on again and the Light turns off. Also once in awhile the car shuts off for no reason when driving down the road. To restart it, it sometimes takes 15 times of turning the key on and off, almost like the fuel pump is told not to turn on.
We put it on a machine and got 2 codes:
P1361- Ignition Control Signal Not Toggling
We are pointing toward Replacing the Ignition Control Module.
Does anyone have any ideas or imput?

When you go to restart, what does the Security light on the dash do. It should come on when you turn the key to "on" and then go off after about 5 seconds. It should not be flashing.
When you turn the key is the car cranking? Is that what you mean by it's not getting gas from the fuel pump?
I've read posts in another discussion by people chasing problems like this. The crankshaft position sensor seems to not give a clear code or sign. For your Ignition Control Module is it getting spark? If it quits and you can remove a spark plug wire to determine it's NOT giving spark would be a great help. Don't just toss on parts. Diagnose (I know, easy for me to say).
The shutting off while running sounds like it _might_ be crankshaft position sensor of camshaft sensor. If the crankshaft sensor gives a problem it _sometimes_ is heat related. Are you in a hot climate? is the car hot when this happens?
People in another discussion have mentioned putting cold water on the crankshaft position sensor (it sits just behind the flywheel and you can throw cold water from a cup on it they've said). Cooling it sometimes gets it back to sensing the timing pieces as they go by.
How many miles on car?

Not every time, but once out of 10 times, I start the car and the check engine light stays on. I then turn the car off and turn it on again and the light goes out.
When the car is hot about 10-15 minutes of driving, it will shut off. I try to start it and it turns over but does not start. Like starting an engine with no gas in it. I will have to check for spark next time it happens.
After around 10-15 tries, it starts right up, no problem. It runs great.
A friend put it on a tester and the codes that came up were:
P1361 Ignition Control Signal not Toggling
P0321 Spark Reference Circuit
P0705 Trans Range Sw Circuit
P1530 A/C Pressure Sw Circuit
It suggested the Ignition Control Module
or the ECM or PCM (Which ever one is the main Brain) I am not quite sure which one. I was going to go to the junk yard and get one. I did replac the Ignition Control Module and the light still comes on , but it hasn't shut off on me yet.
If the crank shaft was the problem, would it have showed up on the tester?

You're into a never never land that seems to have lots of errors but no definite cause. Please don't throw parts at the error codes. Sometimes a good garage diagnostic charge is worth the cost.
The crankshaft sensors don't seem to throw a specific code with their erratic failures.
When car doesn't start you can check the injectors by feeling them during cranking. If you touch them while the car cranks and starts normally you can feel the vibration as they work. If it doesn't do that when it won't start, you know the injectors are getting a signal from the PCM.
The question about the security light was because of the VATS system that turns off the crank and the injectors if the wrong key chip resistance is detected. But if the security light isn't on but works properly during startup it's not likely a problem.
It is possible for PCMs to do funny things. A neighbor had one that gave a terrible rough idle and poor running. But that was a cobbled motor (replacement) to begin with. A replacement PCM from a junkyard did fix the problem.
I'll send an email with a couple of links to places you might want to read about probems and diagnosing to your carspace email box. It's the "mailbox" in the gray horizontal bar at the top of each page here on edmunds.

Thank you very much. You have been a great help. I will have to keep investigating in the problem solving.
#21 of 75 1994 check engine codes
Jan 13, 2008 (10:10 pm)
I have looked all over the internet, and cannot figure a way to get the "check engine light" codes. It's too old for auto zone and other do-it-yourself places, and I don't have $300 for a mechanic to tell me i need a new air filter. I know there are tricks to get the light itself to flash the codes at you, but I can't figure out how. PLEASE HELP!!! I'm a single mom who's mostly mechanically inclined, but I'm still learning.
